I like your idea, very usefull as I dont want to waste some of the nicer paint chips , now I can check how they look before using them. But I think its's much more handy if you make one big .pdf/word file because people now have to scroll trough the topic to find the paint there looking for.
While I don't have pictures (and I don't know if that will ever be a reasonable thing to attempt), check my signature for what is a very thorough Colour Database
